LIN'OTYPE-MACHINE.

Specification of Letters Patent.

Patented Nov. 3, 1914:.

To all whom it may concern Be it known that I, THOMAS S. HOMANS, a citizen of the United, States, residing at Hempstead, in the county of Nassau and State of New York, have invented new and useful Improvements in LinotypeNlachines, of which the following is a specification.

This invention relates to improvements in linotype machines and more especially to the casting mechanism thereof, and one of the primary objects of the invention is to provide an improved mold disk or wheel the gear teeth of which are oll'set with respect to the plane of the mold or molds thereon and the longitudinally adjustable liner of each mold may extend beyond the periphery of the disk or wheel without encountering the supportor guide which serves to sustain the thrust produced on the mold wheel as the slug is carried past the trimming knife, and without requiring cutting away or otherwise mutilating the disk or wheel to accommodate the liner, the liner and the different parts of the moldbeing easily accessible for adjustment or manipulation and weakening of the mold disk or wheel is avoided.

Another object of this'invcntion is to provide the mold disk with pads or lugs which are positioned equidistantly in a direction circumterentially of the disk, such pads affording iaces which serve to positively and invariably set the mold.

A further objeot of this invention is to provide an improved longitudinally adjustable liner for varying the length of the mold cavity, the liner according to the present in vention being flat and avoids grooving of the body of the mold and thereby limiting the adjustment of the mold.

To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as Will be hereinafter more fully described,the novel features being pointed out particularly in the claims at the end of the specification.

In theaccompanying drawing :--Figure l is a perspective view of a mold disk or wheel constructed in accordance with the preferred embodiment of the present invention; Fig. 2 is a view of the mold wheel showing the same edgewisc and partly in section; Fig. 3 shows the mold in elevation, a portion of this figure being in section to illustrate the guiding and positioning key for the improved liner Fig. 4 is an end elevation of the mold and its associated parts; Fig. t is a erspective view of a portion of the mold w eel and the coiSpcr-ating guide or support which sustains the thrust produced upon the mold wheel during the trimming of the slug.

- Similar parts are designated by the same reference characters in the several views.

In the well known linotype machine as generally constructed, the gear teeth on the periphery of the mold disk overlap the plane of the mold or molds thereon, and in using a liner which is adjustable lengthwise ot' the mold to vary the length of the mold cavity, a portion of the periphery of the mold wheel, including the web and the gear teeth, is cut away to provide a clearance for the adjustable liner. the cutting away of the mold wheel in this manner being objectionable as it weakens materially the strength of the disk, particularly the gear portion thereof. lvlorcover. in the linotypc machine as generally constructed, the adjustment of the liner is limited "for the reason that the liner cannot be projected beyond the periphery of the mold disk nor enough to encounter the support or guide which coiipcrates with the circumferenco of the mold disk and sustains the thrust prm'luccd thereon when the slug carried past the trimming knife. These objcclions incidel'it to the linotype machine as heretofore constructed arc obviated by the present invention, and moreover, the mold disk is i-(insiderably stronger. the parts of the mold are readily accessible, and a wide range of adjustment is provided for the liner without interfering with any of the operative parts of the machine. and moreover, simple and effective. means is provided for accurately positioning the mold or molds on the disk.

The preferred embodiment of the invention is shown in-the accompanying drawing and will be hereinafter described in detail, but it is to be understood that the invention is not limited to the particular constructions shown, as different constructions may be used to carry out the principles involved in the present invention.

In the present instance, 1 designates the i in position to cast a slug of type, the foot of the slug, and to eject the or 130? the mold. The n'lold disk en1 hodios a rim Send a Web l, the hub 5 of the ml) cooperating with a supporting shaft 6 hams an axis about i /hich the disk A guide or support 7 attached to a part of the macl ine serves to susthrust produced on the mold disk as i carries the cast slug past the trimto the latter being supported by hraclro' l and is shown in dotted This guiue or support 7 has ch cooperate with the opposite l0 pru'ipheral gear teeth of the and such flanges prevent axial M; (ii the niold disk with re. pect to I: or support. er to permit adequate adjustment which serves to gage the length l cavity Without interference heiner and the guide or support 7 amid dish revolves the peripheral the mold disk, and the mold occupy dil'l'erent planes in off whereby the liner when prorl': Will. clear the guide or support 7 oiliset relation between the mold and the peripheral teeth of the v obviates the necrssit of cutting '1, ti ierehy mutilating and weakening ral portions of the mold disk. nt instance, the peripheral near mold dish are offset Wholly to the plane of the web 4. while the Us related parts are arranged at ide oi" the web, the mold in the n shown comprising a mold body or portion 13 of which may extend LECQSS l l: formed in the web l While "nor portion 15 of the mold body lies the face of the Web 4-. The surface rnold hody 12 serves as one of the of the mold cavity, and the mold ich i s opposed to the mold body 12 opposite side Wall of the mold i'he mold cavity is adjusted to cast flil'fercnt sizes by interposing liners If) hetvscen the mold body and its '1. the length of the mold cavity ina d to cast slugs of different lengths my, one of the liners, the liner 1% tlrcsent instance, in a lengthwise 7 present invention provides an imd adjusta hle liner Which is flat, that is, presents olaue surfaces at top and hottom, 5. this adjustable liner is guided longitufly by a key Which is set in the mold y ef-iahlinp; adjustment of. the liner to f or the mold cavity Without re- :l LLlCQlOIl in the limits of the mold.

1 ill"; construction, the longitudinally ad uster) liner 18 is provided on its under beyond the periphery of the side with a longitudinally extending ke Wav or eroove 26 which terminates short or the :innea end of the liner, and a key 21 is iinmovzihl set or fixed in the niold body the lie cooperating with the lieyway in the liner and thereby guiding and positioning, the same in proper relation to the mold irrespective of the different longitudinal adjust-- ments thereof.

The liners are held in proper position at the opposite ends of the mold by pressure exerted thereon by the mold can 17 and the mold cap in turn is clamped position by suitaliile means. preferably screws, a pair of st ewe coder-rating With the ends of the n in the present instance and a screw iperates with the middle or intermediate ample into the pcripl'leral per i, l of the mold dish and th 1v operate to mzuiu parts of the mold in operative position lVhen it is des'.i.'al3le to vary the lei'igth oi the mold cavity it is only necessary to loosen the screw which exerts a clamping action on the liner l8, the latter may then be shifted longitudinally of the mold to produce the desired adjustment, and tightening of said so no serves to secure and retain the adjustahle liner in the desired adjusted position. l3 loosening all the screws, toe mold cap and both liner may he readil;- removed.

The metritnretaining; ledge or keeper may he appli d to the adjacent use of the mold hod r l2 shov-ui. and ti so two parts may be s cured to the mold l: by a suitable numhi or screws The present nvention provides means for invariably setting or positioning; each mold with respect to the mold disk, s1 1 means embodying prcilm'ahlv a set oi pans or lugs which are located cquidistmtly in a circumferential direction on the face or rich of the mold disk. in the constructi m shown a set of four pads or lugs 26 is provided, the same projecting [rorn the face of the Web 4:, and by spacing these pads or lugs equidistantlv, a mold may be fitted between any pair of the pads. The drawing. shows the mold dish fitted to receive tvvo molds in diametrically opposite relation but itis olwious that one or more molds could be added readilv. Each pad or lug presents a surface 2. ivl iclris adapted to serve as an ahutment for one end of the mold body, and by interposing the mold'bodv between two of the pads, the mold obviously is set or positioned invariably in a longitudinal direction on the mold disk. The adjacent surface 28 of each pad or lug may also serve as a gage to position the mold with respect to the center of the mold disk, these surfaces of the pads when finished accurately serving permanently to insure proper location of the mold with respect to the mold disk and the iso I elements which cooperate with the mold. It is to be observed also that these pads or lugs, being located at the end of the recess 14 which accommodates the mold, serve to reinforce or strengthen the web portion of the mold disk.

T hat is claimed is I. In a machine of the linotype class, in combination with a mold-carrying wheel, a mold having parts adapted to project to the periphery of said Wheel, driving gear teeth on said periphery of the Wheel arranged in offset relation to the plane of the mold, and a guide or support for the wheel cooperative with the marginal portions of said gear teeth and adapted to pass between said mold parts and the adjacent margin of the gear teeth.
